SPECIFICATION forming part of Letters Patent No. 772,572, dated October 18, 1904.

Application filed October 15, 1903.

To a/ZZ whom t may concern:

Be it known that I, OTTO W. MEIssNER, a citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, am the inventor of certain new and useful Improvements in Railway-Cars, of which the following is a specification.

way-cars having transverse beams forming part of the bottom frame of the'car and pro- The principal object of my invention is to provide a simple, economical, and efficient body-bolster and bottom-frame mechanism for railway-cars. l

Other and further objects of the invention ings and the following description and claims. y My invention consists inthe features, combinations, and details of construction hereinafter described and claimed.

, In the accompanying drawings, Figure lis a view in elevation of a body-bolster and transverse-beam mechanism constructed and connected inaccordance with my improvements; Fig. 2, abottom planl view of the bolster, partly` in longitudinal section; Fig. 3, a sectional elevation taken Online 3 of Fig. l look- Ing in the direction of the arrow, showing the bolster and transverse-beammechanism in cross-section and the'longitudinal beams with the filler and binding plates connected to such bolster and transverse-beam mechanism; and Fig. 4f, a sectional view in elevation of the bolster, taken on line 4: of Fig. 2 looking in the direction of the arrow.

In constructing a railway-car provided with a bottom framework comprising transversebeam mechanism and body-bolster mechanism constructed and arranged in accordance with my improvements I provide" av plurality of transverse beams arranged in sets, each-comprising a pair of channel-beams a, whichex tend transversely of the car from side to side thereof and which are connected by means of inserts or connecting-plates-b, riveted to the SerialNo. 177,152. (No model.)

vertical web portions of such channel-beams.

Longitudinal beams c, which may also be rection to the next adjacent set, to which they are attached in a similar manner, and in the My invention relates to that class of rail- A filler-plate CZ is mounted at the under side i of the transverse beams and extends outwardI laterally thereof in engagement with the un-l der side of the longitudinal beams, and an upper binding-plate c extends, preferably, the full length of the transverse beams, upon the upper side thereof, and out laterally ltherefrom in engagement with the upper sides of the longitudinal beams. Side sills f extend the entire length of the-car from end sill to end sill and are connected to the ends of the transverse-beam mechanisms above described by means of angle-plates g and to the end sills in a similar manner. Intermediate longitudinally-extending beams (not shown) extend from one set of transverse beams to theother i at the points indicated by rivets it, by means of which they are attached to such transverse beams, and from the transverse beams to the end sills, to which they are connected in a` -transverse beams and with the filler-plates d,

already described, byV means of rivets, .as shown in Fig. 1. Such upper flange porsertion of the king-bolt into position in the perforations in the upper wall g and the lower wall r of such bolster. The upper bindingplate and filler-plate already described are also provided with corresponding perforations for the purpose of admitting such bolt. Suitable struts s are provided on one side of each bolster, extending outward laterally thereof to the edge of the filler-plate to which they are connected, such struts being attached to the bolster, as shown in Fig. 3, by means of bolts if or in any ordinary and well-known manner, and draft-beams lu are attached to the opposite side of the bolster by means of bolts o and to the longitudinal center beams by means of rivets or in any ordinary and wellknown manner.

The bolster is provided with a central bearing-plate w, which, as shown in Fig. 3, is preferably integral with the main body portion, and side bearings g/ are provided near the opposite ends of the bolster, also, preferably, integral with the main body portion thereof, and at points substantially beneath the points where the intermediate longitudinal beams are connected to the transverse beams. Downwardly-extendingsideportions z, integral with the main body portion of such bolster, form suitable portions for withstanding the strains to which the side bearings are subjected.

The bolster above described, as already suggested, is of less length than the transversebeam mechanism to which it is connected and extends only a sufficient distance toward the opposite side of the car to enable the side bearings to be substantially beneath the intermediate longitudinal beams, so that the Weight of such intermediate beams rests upon or directly over the ends of the bolster. The filler-plate d also extends only to the ends of the bolster, such filler-plate and bolster being firmly attached to the transverse beams by means of rivets 2, which extend through the lower flanges of the transverse beams and through the filler-plate and upper wall or ange of the bolster, as shown in Fig. l. By this arrangement a bottom frame is provided comprising longitudinal and transverse beams having their upper surfaces on substantially the same plane, the intermediate longitudinal beams being supported by the ends of the short bolster, which extends beneath but not beyond such beams. The side bearings of the bolsters are substantially beneath the point of connection between the intermediate longitudinal beams and transverse beams, and such bolster being firmly attached to the transverse beams, as already described, it will be readily appreciated that an economically constructed and comparatively light bodybolster and bottom frame of great rigidity and strength is thus provided.

I claim- 1. In a railway-car, the combination of a bottom frame comprising` a plurality of sets of transverse beams, and a one-piece body-bolster formed of cast metal rigidly connected to the under side of a plurality of such transverse beams, substantially as described.

2. In a railway-car, the combination of a bottom frame comprising a plurality of sets of transverse beams, and a one-piece body-belster for each set of such transverse beams provided with a central longitudinal web portion and having integral upper lateral lianges extending from the upper side of such central web portion and rigidly connected to the under side of such beams, substantially as described.

3. In a railway-car, the combination of a bottom frame comprising a plurality of sets of transverse beams, a one-piece body-bolster for each set of such transverse beams rigidly connected to the underside thereof and provided with integral center and -side bearings, substantially as described.

4. In a railway-ear, the combination of a bottom frame comprising a plurality of sets of transverse beams, a one-piece body-bolster of less length than such transverse beams connected to the under side of each set thereof and provided with center and side bearings on its under side, and a filler-plate interposed between the lower side of such transverse beams and the bolster and connected thereto, substantially as described.

5. In a railway-car, the combination of a bottom frame comprising a lilurality of sets of transverse beams, a one-piece cast-metal bodybolster rigidly connected to the under side of each set of such transverse beams, and alillerplate interposed between the lower side of such transverse beams and thebolster and connected thereto, substantially as described.

6. In a railway-car, the combination of a bottom frame comprising transverse beams extending from side to side of the car, intermediate longitudinal beams having their upper surfaces iiush with the upper surfaces of suoli transverse beams, side sills mounted at the outer ends of such transverse beams, and a one-piece body-bolster rigidly connected with the under side of the transverse beams extending beneath but not substantially bcyond the intermediate center beams and provided with integral side bearings substantially beneath such intermediate longitudinal beams, substantially as described.

7. In a railway-car, the combination of a bottom frame comprising a plurality of sets of transverse beams, longitudinal beams attached thereto having their upper surfaces iiush with the upper surfaces of the transverse beams, and a one-piece body-bolster for each set of transverse beams rigidly attached to the under side thereof and having integral center and side bearings, substantially as described.
